Open Shortest Path First (OSPF) was designed as an （ ） gateway protocol, for use in an autonomous system such as a local area network (LAN). It implements Dijkstra's algorithm, also known as the （ ） path first algorithm. As a link-state routing protocol it was based on the link-state algorithm developed for the ARPANET in 1980 and the IS-IS routing protocol. OSPF was first standardised in 1989 as RFC 1131, which is now known as OSPF version 1.Routing protocols like OSPF calculate the shortest route to a destination through the network based on an algorithm. The first routing protocol that was widely implemented, the （请作答此空）, calculated the shortest route based on hops, that is the number of routers that an IP packet had to traverse to reach the destination host. RIP successfully implemented dynamic routing, where routing tables change if the network topology changes. But RIP did not adapt its routing according to changing network conditions, such as data-transfer rate. Demand grew for a dynamic routing protocol that could calculate the fastest route to a destination. （ ） was developed so that the shortest path through a network was calculated based on the cost of the route, taking into account bandwidth, delay and load. Therefore OSPF undertakes route cost calculation on the basis of link-cost parameters, which can be weighted by the administrator. OSPF was quickly adopted because it became known for reliably calculating routes through large and complex local area networks.As a link state routing protocol, OSPF maintains link state （ ）, which are really network topology maps, on every router on which it is implemented. The state of a given route in the network is the cost, and OSPF algorithm allows every router to calculate the cost of the routes to any given reachable destination. Unless the administrator has made a configuration, the link cost of a path connected to a router is determined by the bit rate (1 Gbit/s, 10 Gbit/s, etc) of the interface. A router interface with OSPF will then advertise its link cost to neighbouring routers through multicast, known as the hello procedure. All routers with OSPF implementation keep sending hello packets, and thus changes in the cost of their links become known to neighbouring routers. The information about the cost of a link, that is the speed of a point to point connection between two routers, is then cascaded through the network because OSPF routers advertise the information they receive from one neighbouring router to all other neighbouring routers. This process of flooding link state information through the network is known as synchronisation. Based on this information, all routers with OSPF implementation continuously update their link state databases with information about the network topology and adjust their routing tables.OSPF has become a popular dynamic routing protocol. Other commonly used dynamic routing protocols are the RIP and the Border Gateway Protocol (BGP). Today routers support at least one interior gateway protocol to advertise their routing tables within a local area network. Frequently implemented interior gateway protocols besides OSPF are RIP, IS-IS, and the proprietary Interior Gateway Routing Protocol (IGRP) by Cisco.A.OSPF

You are a systems engineer for your company. Your company has 20，000 users in a large campus environment located in Los Angeles. Each department in the company is located in its own building. Each department has its own IT staff， which is responsible for all network administration within the building. The company’s network is divided into several IP subnets that are connected to one another by using dedicated routers. Each building on the company’s main campus contains at least one subnet， and possibly up to five subnets. Each building has at least one router. All routers use RIP version 2 （RIPv2） broadcasts. The company acquires a new business unit located in Denver. The Denver office has 25 users. The network in the Denver office is connected to the network at the main campus by using a leased frame relay connection. The network administrator at the Denver office installs a Windows Server 2003 computer and configures Routing and Remote Access on this server. The network administrator at the Denver office configures this server as a router and implements RIPv2 in Routing and Remote Access. Later， the Denver administrator reports that his router is not receiving routing table updates from the routers on the main campus network. He must manually add routing entries to the routing table to enable connectivity between the locations. You investigate and discover that the RIPv2 broadcasts are not being received at the Denver office. You also discover that no routing table announcements from the Denver office are being received on the main campus network. You need to ensure that the network in the Denver office can communicate with the main campus network and can send and receive automatic routing table updates as network conditions change. What should you do on the router in the Denver office？（）A、 Configure the router to use RIPv1 broadcasts.B、 Configure the router to use auto-static update mode.C、 Add the IP address ranges of the main campus network to the router’s Accept list and Announce list.D、 Add the IP addresses of the main campus routers to the router’s Neighbors list.
